Abstract
The utility model relates to a heparin cap for cell infusion and a cell infusion device. The heparin cap is characterized in that: the output end of the heparin cap is provided with a filter screen by which cell aggregates are stopped. The utility model has the advantages that: (1) the improved heparin cap and the cell infusion device can filter infused cells, so the cell aggregates can be prevented from entering a human body, and the relevant particle danger can be prevented; (2) by using the cell infusion device, cytochylema can be diluted, infusion is facilitated, and the cell aggregates can be prevented from being regenerated; and (3) by the relevant operation, the cell infusion device can prevent cells from being adhered to the filter screen and can disperse the cell aggregates to ensure that the cells are infused into the human body in the form of single cell or two cells, so infusion is greatly facilitated, and the residual amount f the cytochylema is effectively reduced.
Description
Technical field
This utility model relates to a kind of cell infusion with calparine cap and cell infusion device.
Background technology
When carrying out cell infusion such as mescenchymal stem cell, because iuntercellular is prone to form cell mass, cell mass gets into human body with infusion, endangers and bring like microgranule dependencys such as granulomas.
Summary of the invention
The purpose of this utility model be to provide a kind of can filter the infusion cell of forming agglomerate and dispersive cell infusion with calparine cap and cell infusion device.
The purpose of this utility model realizes through following technical scheme:
A kind of cell infusion is used calparine cap, it is characterized in that: the outfan of said calparine cap is provided with and is used for preventing the filter screen that cell mass passes through.
A kind of cell infusion device; It is characterized in that: it comprises indwelling needle assembly, three way cock, be connected in connection tube between indwelling needle assembly transfusion arrival end and the three way cock's outfan and the calparine cap that is connected with three way cock's a input, and the outfan of said calparine cap is provided with and is used for preventing the filter screen that cell mass passes through.
The method for using of the said cell infusion device of this utility model is following:
Cell sap after the filtration of drainage screen, gets into the three way cock by the input input of calparine cap; Another input of three way cock is connected with the diluent tube for transfusion, imports diluent simultaneously, and the Cell sap that gets in the three way cock is played dilution, souring, avoids cell mass to generate once more; Through the blocking-up connection tube, diluent is got in the calparine cap, play the effect of flushing filter screen, avoid cell attachment on filter screen, the cell mass that is intercepted by filter screen is scattered under the diluting effect of diluent, effectively reduce the residual volume of Cell sap.
Compared to prior art, the advantage of this utility model is:
(1) calparine cap and the cell infusion device after the improvement can filter the infusion cell, avoids cell mass to get into human body, prevents the generation of microgranule dependency harm;
(2) through the use of cell infusion device, can dilute by pair cell liquid, be convenient to infusion, and avoid cell mass to generate once more;
(3) the cell infusion device can avoid cell attachment on filter screen through associative operation, and the cell dispersion agglomerate, makes cell go into human body with unicellular or two cell infusion, greatly facilitates infusion, effectively reduces the Cell sap residual volume.

The specific embodiment
Below in conjunction with Figure of description and embodiment this utility model content is elaborated:
The cell infusion that provides for this utility model as depicted in figs. 1 and 2 is with the embodiment sketch map of calparine cap.
A kind of cell infusion is used calparine cap, it is characterized in that: the outfan of said calparine cap 1 is provided with and is used for preventing the filter screen 2 that cell mass passes through.
The radial section of said filter screen 2 is curved, and said arc protrudes to calparine cap 1 input direction.
The mesh diameter of said filter screen 2 is 70 microns.
Said filter screen 2 by the pair cell adsorptivity a little less than or not the material of adherent cell process.
Like Fig. 3, Fig. 4 and the cell infusion that provides for this utility model shown in Figure 5 embodiment sketch map with calparine cap.
A kind of cell infusion device that has cell infusion with calparine cap; It comprises indwelling needle assembly 3, three way cock 4, be connected in connection tube 5 between indwelling needle assembly 3 transfusion arrival ends and three way cock's 4 outfans and the calparine cap 1 that is connected with an input of three way cock 4, and it is characterized in that: the outfan of said calparine cap 1 is provided with and is used for preventing the filter screen 2 that cell mass passes through.
The radial section of said filter screen 2 is curved, and said arc protrudes to calparine cap 1 input direction.
The mesh diameter of said filter screen 2 is 70 microns.
Said filter screen 2 by the pair cell adsorptivity a little less than or not the material of adherent cell process.
Said calparine cap 1 is be removably connected (like Fig. 3) with three way cock 4.Perhaps said calparine cap 1 is connected (like Fig. 4 and Fig. 5) with three way cock 4 for integral type.
